However, if you don’t have control over when you go you should pack something like this rain poncho. They lay flat and are easy to pack. This is one of those things you’ll kick yourself for not throwing it in your bag. Imagine you’re on a walking tour of Tulum and, BOOM! A quick rain shower. No thanks! I’ll pack that poncho all day in my handy-dandy backpack.
